What Our Gearhead(R) Experts Are Saying: "This is one of my go-to jerseys for long, hot summer rides. The Polartec Delta fabric really does keep things cooler, and I love the Cordura sleeve panels for bashing through overgrowth without worrying about snags. It fits like it was made for the saddle position-no bunching, just all-day comfort."When temps climb and the trail beckons, we gear up in the Fox Attack Jersey for its unmatched blend of airflow and durability. Built with Polartec Delta, this high-performance fabric doesn't just wick sweat-it actively cools us down as we climb, descend, and hammer through heat-soaked terrain. Fox engineered this jersey for real trail conditions, reinforcing the sleeves with tough Cordura fabric to resist abrasions from brush and branches. The four-way stretch ensures freedom to move, while laser-cut ventilation and a bike-specific fit keep airflow dialed and comfort locked in through every mile of dirt.
